how we will move if we are on polar region and there is no friction?

Expert Answer:

Dear Student,
We cannot move if there is no friction. As you pointed out polar regions,
Ice is not a perfectly frictionless surface, of course: otherwise, skating would be impossible. Likewise friction   is absolutely necessary for walking, as you can illustrate by trying to walk on a perfectly slick surface—for instance, a skating rink covered with oil. In this situation, there is still an equally paired set of forces—your body presses down on the surface of the ice with as much force as the ice presses upward—but the lack of  friction impedes the physical process of pushing off against the floor.
Hope this helps.
Thanking you
